Observing Notes

Captain William Henry Smyth
Aug 29, 1837    No. 6 The Crescent, Bedford, England (map)
150mm f/17.6 refractor by Tully 1827

A minute double star, in a cluster [NGC 457] between the Lady's right knee and her elbow. A 9, and B 10, both white [BD+57 249 mag 9.83 and BD+57 248 mag 10.16]. This brilliant aigrette-shaped group of large and small stars, was discovered by William Herschel on the 18th of October, 1787, and is No. 97 of John Hershel's Catalogue. In the centre is the fine double star before us, the position and distance of which are very carefully estimated. There is a star of the 7th magnitude at the sf verge of the field [HD 7902 mag 6.96], which is very bright and white. The cluster is close to φ, and though differentiated from that star, was also observed with the meridian instruments.
